Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace CV Joints

Lift the Vehicle: Use the jack to lift the front of the Highlander and secure it on jack stands.
Remove the Wheel: Use the socket set to remove the lug nuts and take off the front wheel to access the CV joint.
Examine CV Joint: Check the CV joint for any cracks or tears in the boot. If damaged, proceed to replace.
Remove the CV Axle:
- Remove any retaining clips or bolts securing the axle to the hub and transmission.
- Gently tap the axle out of the hub using a pry bar if necessary.
Install New CV Joint:
- Slide the new CV joint into the transmission and secure with the retaining clip.
- Reattach to the hub and torque to manufacturer specifications.

3. Inspect and Tighten Suspension Components

Check Suspension Bolts:
- Inspect all bolts and nuts on the control arms, sway bar links, and struts.
- Tighten any loose fasteners to the specified torque values.
Replace Worn Components: If any suspension parts are worn, replace them as needed.

4. Reassemble and Lower the Vehicle

Reattach the Wheel: Place the wheel back onto the hub, hand-tighten the lug nuts.
Lower the Vehicle: Carefully remove the jack stands and lower the vehicle.
Torque Wheel Lug Nuts: Once the vehicle is on the ground, torque the lug nuts to the manufacturer’s specification.
